世界の時間を表示する

世界中の時間を表示します。
worldsDataに場所と日本からの時差を入れます。

<div id="world-time"></div>

const worldsData = [
  {
    location: "東京",
    TimeDifference: 0
  },
  {
    location: "ベルリン",
    TimeDifference: -8
  },
  {
    location: "上海",
    TimeDifference: -1
  },
  {
    location: "ニューヨーク",
    TimeDifference: -14
  },
  {
    location: "ロサンゼルス",
    TimeDifference: -16
  },
]
const content = document.getElementById('world-time');

worldsData.forEach(function (world) {
  const now = new Date(new Date().getTime() + world.TimeDifference * 60 * 60 * 1000);
  const year = now.getFullYear();
  const month = now.getMonth() + 1;
  const day = now.getDate();
  const hour = now.getHours();
  const minu = now.getMinutes();
  
  const divElement2 = document.createElement('div');

  divElement2.innerHTML = `
  <ul>
    <li>${world.location}</li>
    <li>${`${year}年${month}月${day}日 ${hour}:${minu}`}</li>
  </ul>
  <br><br>
  `
  content.appendChild(divElement2)
});
